Prevention for Positives

Case 4: STDs and HIV Transmission

You answered:

The presence of genital lesions caused by HSV in an HIV-infected
person confers a major increase (up to 4-fold) in the risk of HIV
transmission to a HIV-negative partner.

This answer is correct. The presence
of a recent genital ulcer caused by HSV is associated with an approximate
4-fold increased risk of transmission of HIV per-sex-act in couples who
are serodiscordant for both HIV and HSV-2.
